In a motherboard assembly line, just about every of the factors in the circuit board are normally shielded by its respective circumstance. This scenario, as element of the total process, is also called a motherboard or mom-circumstance.
Due to the fact the circuit board is an vital section of the motherboard, the circuit board have to be secured against external pressure and heat for the duration of the assembly approach.
The motherboard assembly course of action generally consists of two actions:
Attaching the circuit board to the motherboard and connecting the circuit board to the motherboard. The circuit board and the motherboard are generally hooked up jointly by an adhesive or a fastener. The circuit board is related to the motherboard by an electrical connector. The procedure of connecting the circuit board to the motherboard can be a time consuming process, especially when the motherboard has a substantial number of components.
The process of connecting the circuit board to the motherboard can be simplified if the circuit board and the motherboard are previously linked alongside one another. The circuit board and the motherboard are already related with each other, and they are not hooked up to every other. The system of connecting the circuit board to the motherboard is called a self-hook up method.
The approach of self-connecting the circuit board to the motherboard can be performed in two methods:
1) by specifically connecting the circuit board to the motherboard
(2) by eliminating the circuit board from the motherboard and then immediately connecting the circuit board to the motherboard.
Motherboard have to be put in into the scenario
In the assembly course of action, the motherboard need to be mounted into the circumstance and fastened by the screw. Soon after the screw is tightened, the motherboard is secured in the case. At this moment, the motherboard is commonly vibrated by the vibrator, and the vibration of the motherboard will be transmitted to the screw. The vibration will be transmitted to the screw and will make the screw loosen or even free. When the screw loosens, the motherboard is loosened and may well be weakened. This is a typical issue of the motherboard assembly line.
In order to fix the above challenge, a amount of regular procedures are proposed. For case in point, U.S. Pat. No. 6,775,708 discloses a motherboard assembly line obtaining a vibration and influence absorbing procedure. In the process, a motor and a screw are supplied. The motor is employed to drive the screw to rotate and tighten the screw. The screw is a prolonged screw getting a head and a screw entire body. The screw human body is manufactured of steel.
Why case is essential to be developed with a high precision?
For the reason that the scenario is an integral element of the full motherboard, it is necessary to be made with a higher precision. Therefore, the sizing and the condition of the circumstance are commonly created in accordance to the specifications of the motherboard and the place of the parts on the motherboard.
The motherboard cover is typically a rectangular parallelepiped body with a plurality of mounting holes. The motherboard cover is manufactured of a plastic substance, and the plastic material is typically a plastic materials that is really hard to be scratched. The plastic product has a great put on resistance. The motherboard deal with is supplied with a plurality of screw holes corresponding to the mounting holes of the motherboard human body.
